PAPER-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 431,771, dated July 8, 1890.

Application filed August 22, 1889 Serial No. 321,653. (ModeL) To all whom it may concern.-

Be it known that we, W'ILLIS O. JONES and JOHN G. D. MACK, of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Paper-IVinding Machines, of which the following is a specification.

It is often desired in dealing with paper, and also with webs of other material, to take a roll of wide paper and to slit the wide Web into two or more narrower webs, which are wound into independent rolls. Machines for accomplishing this generally consist of two or more winding-shafts, on which the narrower webs are wound, these shafts being revolved by power, the narrow webs winding upon these shafts and drawing their supply from the roll of wide paper, the separation of the wide web into narrower ones being effected by means of slitters acting on the paper between the single roll of wide paper and the several rolls of narrower paper. The paper will leave the wide roll as fast as it may be pulled off by the winding of the narrower rolls. The narrower rolls of paper increase in diameter as they receive paper, and consequently the peripheral speed of these narrower rolls, and also the speed of unwinding from the wide roll, increases as the winding progresses upon the narrower rolls. One of the narrower rolls may have a different diameter from that of any of the other narrower rolls, and as all must draw their supply of paper at the same speed from the single wide roll it follows that the velocity of rotation of the several narrower rolls must be related to each other inversely as the diameter of those rolls, and that this relation-. ship is constantly changing. It has long been customary in the winding of paper and other webs in this manner to provide means by which the proper relationship between the velocity of 'the several narrow rolls becomes automatically adjusted. The means employed for effecting this adjustment have consisted in some cases of frictional driving devices and in other cases of surfacedriven rolls, and in other cases of well-known equational boxes, and in other cases of selfadjusting idlers on the driving-belts. The equational box has long been employed where and the strain restored to the idle-winder.

The equational box has also the merit of imposing equal strains upon the several winders where but two winders are used. WVhere more than two winders are employed, the equational box has been employed between each pair of winders and another equational box has 'been introduced between each pair of pairs of winders. By these means two or any geometrical ratio of two winders could be operated; but the equational box has never, so far as we are aware, been rendered operative in driving an odd number of winders under equal strain. When attempts have been made to drive an odd number of winders through an equational box, it has been found necessary to add an artificial resistance to one of the winders to make it balance the load represented by a greater number of winders opposed to it on the other side of the equational box.

By means of our invention we deal with any desired odd or even number of winders. Ve drive them through the medium of equational boxes. We operate all the winders at once, or we operate any number less than the whole without the necessity for imposing any artificial resistance upon any one of the running winders, whether the number running be odd or even.

Our invention will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure l is a plan of a paper-winding apparatus provided with three winding-shafts, one of these shaft H being illustrated as out of action and not in use; Fig. 2, a side eleva tion of the same; Fig. 3, a front elevation of the counter-shaft from which the winders are driven, this counter-shaft carrying three driven pulleys R, S, and T, the pulley R appearing in vertical section in the plane of line a of other figures, while the pulleys S and T expose vertical sections in the planes, respectively, of lines b and c of other figures; Fig. 4, a face view of the pulley S shown as detached from the counter-shaft; and Fig. 5, a plan similar to Fig. 1, but showing the three winding-shafts in use, the paper being slitted into two slits and wound into three rolls instead of two, as in Fig. 1.

The construction of the machine illustrated is a mere exemplification of our invention.

The counter-shaft gives motion to all the pulleys in the direction of motion. indicated normally at the same velocity of rotation. The effect is obviously to rotate all the windupon the several winders and so modify their velocities as to effect such equalization of- ,duty. Assume now that, asillustrated in Fig. l,

we desire to use only the winders F G. We

tighten the setrscrew N, thuslocking the tailshaft of winder H absolutely against rotation.

This alsoresultsinlocking the pulleyTagainst rotation. Turn now to Fig. 3, andimagine the pulley T locked against rotation, while the counter-shaft revolves in the direction of the arrow h.

Pulleys R and S will revolve in the directions indicated by their arrows and will transmit motion to the winders F and G and will equalize the duty between them. On the ers' uniformly; but those familiar with the qualities of the equational boxes involved will, upon an analysis, understand that the tendency of the device is to equalize the duty same principle the counter-shaft may be pro-- vided with any desired odd number of pulleys, which may be employed in transmitting motion to a similar number of winding-shafts. The entire lot of winders maybe used at once, or any number of them desired maybe locked out of action, leaving the others to be driven and used. It will at once be seen that the very principle of 'our invention abandons at once the apparently-established theory that equational boxes must be made to deal with pairs or with pairs of pairs or that yielding artificial resistance must be imposed upon an odd winder to bring the duties into equilibrium.

We now proceed to a constructional analysis of the device illustrated in Fig. 3. The counter-shaft is a rotary one, and the terminal gears V and g are fast on the counter-shaft and revolve with it. The counter-shaft, so far as its rotary quality is concerned, is therefore a mere expedient for giving rotation in the same direction and at equal speeds to these two gears. gears V and 9 may be produced in any other way desired. In practice we have employed a non-rotary counter-shaft, and have driven the two gears V and g by two belts engaging pulleys secured directly to the gears which were then, of course, loose upon the countershaft.

Assume now that, instead of using thethree winders at once the winder F is not wanted, and that it becomes the duty of the countershaft to transmit motion only to the remaining winders. In such case we tighten the setscrew L, Fig. 1, and thus lock the pulley R positively against rotation. The set-screw is thus merely a means for absolutely preventing the rotation of the pulley R, and any means for accomplishing this result will answer. Turn now to Fig. 3 and analyze the device, on the assumption that pulley R is incapable of rotation. Gear 9 is revolving in the direction of arrow h, and, through the medium of planetary gear f, having no longer a planetary motion, drives double gear de in a direction the reverse of arrow 71, but at the same speed as the counter-shaft, the object being to get the desired eifect upon the planetary wheel Z. Thus it willbe seen that under the conditions named the gears g, f, and e and the stationary pulley R constitute merely a means for getting rotary motion to the gear cl at fundamental speed and in a direction the reverse of that of gear V. When therefore less than the whole number of countershaft pulleys is to be employed in transmitting motion to the winders, it is only necessary to substitute for the idle counter-shaft pulleys a means for properly rotating the bevel-gears, which engage the planetary gears of the pulleys which are actually employed. The idle-pulleys, locked against rotation and provided with their bevel-gears, furnish such This motion of the two .ing-gears means. Obviously, if pulley R is not to be used and the only office of it and its gears is to revolve the gear 01 in a certain direction at a certain definite speed, a belt-pulley se cured to gear (I and properly driven will answer the purpose in case permanent provision is needed only for the employment of pulleys S and T.

It'is to be understood, of course, that the counter-shaft pulleys and the tail-shaft pulleys and the belts engaging these pulleys are mere mediums for transmitting rotary motion from the counter-shaft to the winders, and that spur-gearing or other equivalent transmitting mechanism might be employed.
